Subject: memory mode information now contained in system object States are now
 running, draining, or drained. memory state information moved into system
 object system parameter is not fs only for cpus Implement drain() support in
 devices Update for drain() call that returns number of times
 drain_event->process() will be called

Break O3 CPU! No sense in putting in a hack change that kevin is going to remove in a few minutes i imagine

src/cpu/simple/atomic.cc:
src/cpu/simple/atomic.hh:
    Since se mode has a system, allow access to it
    Verify that the atomic cpu is connected to an atomic system on resume
src/cpu/simple/base.cc:
    Since se mode has a system, allow access to it
src/cpu/simple/timing.cc:
src/cpu/simple/timing.hh:
    Update for new drain() call that returns number of times drain_event->process() will be called and memory state being moved into the system
    Since se mode has a system, allow access to it
    Verify that the timing cpu is connected to an timing system on resume

src/dev/sinic.hh:
    Implement drain() support in devices
src/python/m5/config.py:
    Allow drain to return number of times drain_event->process() will be called. Normally 0 or 1 but things like O3 cpu or devices with multiple ports may want to call it many times
src/python/m5/objects/BaseCPU.py:
    move system parameter out of fs to everyone
src/sim/sim_object.cc:
src/sim/sim_object.hh:
    States are now running, draining, or drained. memory state information moved into system object
src/sim/system.cc:
src/sim/system.hh:
    memory mode information now contained in system object

Subject: add system.mem_mode = ['timing', 'atomic'] update scripts acordingly

configs/test/SysPaths.py:
    new syspaths from nate, this one allows you to set script, binary, and disk paths like
    system.dir = 'aouaou' in your script
configs/test/fs.py:
    update for system mem_mode
    Put small checkpoint example
    Make clock 1THz
configs/test/test.py:
src/arch/alpha/freebsd/system.cc:
src/arch/alpha/linux/system.cc:

src/arch/alpha/tru64/system.cc:
src/arch/sparc/system.cc:
src/python/m5/objects/System.py:
src/sim/system.cc:
src/sim/system.hh:
    update for system mem_mode
src/dev/io_device.cc:
    Use time returned from sendAtomic to delay
